Laravel使用'With'子句将参数从控制器传递到模型 [英] Laravel pass parameters from controller to Model using 'With' clause
问题描述
我是Laravel的新朋友, 我想使用with子句
I am new in Laravel, I want to pass the the $id from my controller in the model using with clause
我的模特
class Menucategory extends Model
{
protected $fillable = ['title', 'parent_id', 'restaurant_id'];
// loads only direct children - 1 level
public function children()
{
return $this->hasMany('App\Menucategory', 'parent_id');
}
// recursive, loads all descendants
public function childrenRecursive()
{
return $this->children()->with('childrenRecursive');
}
}
我的控制器
public function show($id)
{
$menucatagories = Menucategory::with('childrenRecursive')->where('restaurant_id',$id)->where('parent_id','0')->get();
return $menucatagories;
}
我当前的输出是
[
{
"id": 1,
"title": "TestMenu Parant",
"parent_id": 0,
"restaurant_id": 12,
"children_recursive": [
{
"id": 2,
"title": "TestMenu SubCat1",
"parent_id": 1,
"restaurant_id": 12,
"children_recursive": [
{
"id": 6,
"title": "TestMenu other sub cat",
"parent_id": 2,
*******************
"restaurant_id": 13,
*******************
"children_recursive": []
},
{
"id": 7,
"title": "TestMenu other sub cat",
"parent_id": 2,
"restaurant_id": 12,
"children_recursive": []
}
]
},
{
"id": 3,
"title": "TestMenu SubCat2",
"parent_id": 1,
"restaurant_id": 12,
"children_recursive": []
}
]
}
]
我通过了$id=12
,但是问题是我在子数组中获得了其他restaurant_id
的值,但是如果我使用它,它将显示正确的jSON
I passed $id=12
, but the problem is I get the values of others restaurant_id
in my child array, but if i use this it shows the correct jSON
public function childrenRecursive()
{
$id=12;
return $this->children()->with('childrenRecursive')->where('restaurant_id',$id);
}
我的问题是如何将$ id从控制器传递给模型,或者有其他方法吗?
my questions is how can i pass the $id from the controller to the model or is there any other approach?
推荐答案
您的childrenRecursive
完全没有错.
在这里看到一个类似的示例: https://stackoverflow.com/a/18600698/2160816
See here an simliar example: https://stackoverflow.com/a/18600698/2160816
所以我认为这应该起作用
So I think this should work
public function childrenRecursive($id = 12){
return $this->children()->where('restaurant_id',$id)->with('childrenRecursive');
}
您的控制器随后可以呼叫
Your Controller then could call
public function show($id)
{
$menucatagories = Menucategory::where('parent_id','0')->childrenRecursive(12)->get();
return $menucatagories;
}
我无法对其进行测试,因此可能无法100%工作
I could not test it so may it won't work 100%
